FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 261,075, dated July 11,1882.

Application filed February 28, 1882. (No model.)

To all whom it may concern Be it known that I, SARAH TONER BARR, acitizen of the United States, residing at Wash ington city, in theDistrict of Columbia, have invented a new and useful Fire-Escape, ofwhich the following is a specification.

The object of my invention is to have an 4 easy means of escape frombuildings in case of tire; first, by providing a fire-proof foldingladder; second, to have it securely fastened to its place under thewindows on the inside of the building, and at the same time folded awayin convenient form ready for immediate use. I attain these objects bythe mechanism illustrated in the accompanying drawings.

Figure 1 is an outside view of the window with the escape attached readyfor use. Fig. 2 is the inside of the window, showing how the escape isattached to the wall under the window and the escape folded up on thefloor. Fig. 3 shows the fastenings on the outside of the wall,whethercross-head bolt, nuts, or keys.

The sides A A and the cross-pieces B B constitute the frame-work of theescape.

The two chains 0 G, fastened to the sides A A, are attached to tworing-headed bolts, D D, of suficient length to pass through the wall ofthe building under the window-sills, entering from the inside. The boltsare fast ened on the outside of the wall by a screwnut, a cross-head, ora key, which may vary according to the condition of the wall.

The sides A A and the cross-pieces B B are made of iron or steel rodslooped together so as to allow a complete fold at each joint. For thispurpose the side bars, A A, and rounds B B are formed with loops orrings on the ends thereof, as clearly seen in Fig. 1. As there are buttwo meeting ends on each side where the top and bottom roundsjoin theside bars, thejoint will be two-looped, so far as these rounds are inquestion, but all the other side bars and rounds will be joined togetherby a three-looped joint, and when the chains are fastened to the upperside bars all joints will be three-part except at thelower round. Theside joints are about sixteen (16) inches long ilnd the cross-piecesabout twelve (12) inches ong.

The chains 0 0, attached to the upper end of the escape and to the boltswhich pass through the wall, are iron or steel chains about three feetlong, the lengtlrbeing principally regulated by the size of thewindowsills, (under which the ring-headed bolts enter the wall,) overwhich window-sills the chains pass when the escape is set for use. Thesechains are of the same width apart as the side bars of the escape, thusthe swaying motion from side to side will be reduced to a minimum.

Wooden balls E E, four inches in diameter, are placed on the uprights AA whenever the escape lies too close to the wall to allow a foot-rest.These balls are movable along the uprights, so as to allow the escape tofold up closely, and when the escape is set for use the balls fall totheir place at the lower end of the uprights A A. The wooden balls aresu perior to anything I know of for keeping the ladder away from thewalls. They are strong and simple, and the ladder will not tip soeasily, but would rather have a swaying motion.

Fig. 4 shows a front elevation of a four (4) story building with theescape set from third and fourth story windows to show the position ofthe wooden balls. These balls are only necessary where the projection ofthe windowsills are not sufficient to keep the escape out from the wallbetween the lower part of one window and the top of the window below it.

I am aware that prior to my invention adjustable fire-escapes have beenmade and patents therefore granted, also that wooden wheels have beenplaced upon the wooden rounds of a fire-escape to keep the same from thewalls of the building; but I am not aware that the features of myinvention have been used.

What I claim, and desire to secure by Letters Patent ot the UnitedStates, is-

1. In a folding fire-escape, the wooden'balls placed at intervals uponthe side bars and movable thereon, substantially as set forth.

2. In a folding fire-escape, the side bars, A A, and rounds B B,combined together by a three-looped joint, the former having movablewooden balls thereon at intervals, as shown, and for the purpose setforth.

3. The herein-described fire-escape, consisting of the chains 0 G,suitably fastened to the bars at intervals and movable thereon,subbuilding and joined to the ladder, so as to be stantially as setforth.

the same width apart as the side bars the Y metallic side bars, A A, androunds B B, n iade SARAH DOB DR BARR 5 to open and close easily byhaving their ends Witnesses: 4

constructed to form a three-looped joint, and JOHN E. BEALL, the woodenballs E E, placed upon the side J. M. TONER.
